Historical low pressure events - central southern England

Today's minimum MSL pressure here was 961.1 mbar at 1405z (value from
Fortin mercury barometer, backed up by PAB 961.2 mbar and Davis AWS
value of 960.9 mbar). This is the fourth-lowest value in southern
England west of London within the last 60 years (see details below).
It is still 9 mbar higher than the Feb 1989 event, which was the
lowest in London since 1821.
Thanks for that, I was wondering how Monday rated historically in my
part of the World. I recorded 962 mb just after 2pm - Solent MRSC
reported 963 at the same time so I *may* have been correct (I am a few
miles NNW of there).
At 1pm (high tide in the Solent) I was out at Hillhead Sailing Club
near Lee-on-the-Solent and I have a couple of photos illustrating the
effects of these pressures and winds at a Spring High Tide, even in
the very sheltered Solent. Nearby Portsmouth recorded a high tide 0.7m
above the predicted Spring Tide level and the earlier (6-7 am) low
tide was a full metre above the prediction. Lucky the tides weren't
reversed.
Hillhead coast road is almost indistnguishable from the harbour:
